In a sample of 50 business trips taken by employees in the HR department, a company finds that the average amount spent for the trips was $1450 with a standard deviation of $450. In a sample of 90 trips taken by the employees in the sales department is S1650 with a standard deviation of $700. When testing the hypothesis that the average amount spent on trips taken by the sales department are higher than those taken by the HR department, if the test statistic is 2.05 and the critical value is 2.57 then what is your conclusion concerming the null hypothesis?
